Robin Thicke threatened to pull out of a New Year’s Eve appearance at SLS Hotel South Beach because he thought his room was too small.

The “Blurred Lines” crooner was booked to perform and host a party at the Miami hotel and checked in Monday. But we’re told Thicke was dissatisfied with his digs and demanded to be moved.

“He threatened to pull out if he didn’t get a bigger room,” a source said. “His travel agent was calling all over Miami to get him a bigger room at a different hotel.” But a rep for the SLS denied the drama, saying, “Robin has been a great guest.”

Thicke played the Gatsby-themed bash with Skylar Grey.
On Sunday, Thicke and his wife, Paula Patton, could have used a room before heading to Miami. Spies at 1Oak in Las Vegas told us the couple were “too busy kissing and hugging” during Major Lazer’s performance to pay attention to the show. “No one could interrupt them. Fans were coming up to them, but the couple ignored them,” said a spy. “The only time they broke away from each other was when Thicke went to the DJ booth to yell ‘Happy New Year.’ ”

Good thing they worked out the whole room situation.

Those two are always all over each other. And it was a Major Lazer show? Molly HAD to be a factor.
